20.8. Monitor JBoss Enterprise Application Platform 6 Applications Using Library Mode

A correctly configured instance of JBoss Operations Network (JON) 3.1.x or better.

A running instance of JBoss Operations Network (JON) Agent on the server where the application will run. For more information, see Section 20.4, “JBoss Operations Network Agent”

An operational instance of the RHQ agent with a full JDK. Ensure that the agent has access to the tools.jar file from the JDK in particular. In the JBoss Operations Network (JON) agent's environment file (bin/rhq-env.sh), set the value of the RHQ_AGENT_JAVA_HOME property to a full JDK.

The RHQ agent must have been initiated using the same user as the JBoss Enterprise Application Platform instance. As an example, running the JBoss Operations Network (JON) agent as a user with root privileges and the JBoss Enterprise Application Platform process under a different user does not work as expected and must be avoided.

An installed JBoss Operations Network (JON) plugin for Library Mode. For more information, see Section 20.6.1, “Installing the JBoss Operations Network Plug-in (Library Mode)”

A custom application using Red Hat JBoss Data Grid's Library mode. This application must have jmxStatistics enabled (either declaratively or programmatically). For more information, see Section 19.4, “Enable JMX for Cache Instances”

The Java Virtual Machine (JVM) must be configured to expose the JMX MBean Server. For the Oracle/Sun JDK, see http://docs.oracle.com/javase/1.5.0/docs/guide/management/agent.html

A correctly added and configured management user for JBoss Enterprise Application Platform.
